our company is setting up VPN for our company network
and i am thinking about setting up an OEM at my home computer to access our test oracle db.

there is a few points i don't understand so far:

1. if VPN is setup, there would be 2 network connection (internet & VPN)

how would tnsnames.ora be set up to use VPN instead of internet connection?

it would be great if someone can forward me to some doc or website regarding this
